cancer cells. The decoration of nanoparticles with tumor targeting molecules, such as hormones, growth factors etc. can increase the efficacy of a treatment. Integrin, EGFR are usually the target receptors.
Figure 3 A description of passive and active targeting. Blood vessel near tumor is not well organized, and numbers of pores are found. EPR effect is observed only at the tumor tissue. Thr

폐암은 주로 한쪽 폐로부터 시작하여 임파절, 그리고 폐내의 다른 조직들로 전이되고, 결국은 양폐 모두로 확산되는데, 임파절이나 혈액을 통하여 몸 전체로도 확산될 수 있다. 폐암이 잘 전이되는 장기로는 뼈, 뇌, 간, 부신, 신장,
Virus is
Small infectious agent that can replicate
only inside the living cells of organisms
Life Properties are
“Organisms at the edge of life“
Do not have their own metabolism
Do not have a cellular structure
Possess genes and evolve by natural selection
Reproduce by creating multiple copies
Assembled within cells
Oncovirus is
Virus that can cause cancer

STEP1: ABOUT SKIN CANCER
Cause of cancer _ 2 cases
1.Cell growth doesn’t stop
2.Disorder of apoptosis
p53 : Tumor repressor gene
P53 : transcription factor
Functions
-p53 are that first arrest cell cycle so control cell growth, also active apoptosis suicide program
P53 mutation ->p53 sytem breaks down, it can’t act as Transcriptor factor-> generating tumor
1. cancer의 발생기전
①initiation(시작) : carcinogen(발암물질)이 DNA에 손상을 줄 때 발생한다. carcinogen은 유전적 또는 분자 수준에서 cell의 기능과 구조에 변화를 야기한다. 이런 손상은 가역적이고 또는 회복되지 않는다면, 유전적 mutation을 가져올 수 있다. 그러나 mutation은 즉각적으로 cancer을 이르게 하는
